0x05
|
Quasi-Zenith Satellite System (Japan). |
QGeoSatelliteInfo::Multiple
|
0xFF
|
This type normally indicates that the information is received from a device that supports multiple satellite systems, and the satellite system is not explicitly specified. Depending on the data source, you might use other information to determine the actual system type. One example of the usage of this type is an NMEA $GNGSA message, which contains the IDs of the satellites being used, but does not explicitly mention their system types. |
QGeoSatelliteInfo::CustomType
|
0x100
|
The first type that can be used for user purposes. For example when reimplementing NMEA data parsing in
QNmeaSatelliteInfoSource
. User can add more types using
CustomType + 1
,
CustomType + 2
and so on.

QGeoSatelliteInfo::
QGeoSatelliteInfo
(
QGeoSatelliteInfo
&&
other
)
Creates a satellite information object by moving from other .
Note that a moved-from QGeoSatelliteInfo can only be destroyed or assigned to. The effect of calling other functions than the destructor or one of the assignment operators is undefined.
This function was introduced in Qt 6.2.

返迴衛星標識符編號。
The satellite identifier number can be used to identify a satellite within the satellite system.
The actual value may vary, depending on the platform and the selected backend.
例如，若 nmea plugin is used, the satellite identifier for GPS satellite system represents the PRN (Pseudo-random noise) number, and the satellite identifier for GLONASS satellite system represents the slot number.
For NMEA-based backends the satellite identifier can be used to determine the satellite system type if it is not available from other sources. You can refer to satellite IDs list to check the ID ranges for different satellite systems.
注意： Depending on the platform and the selected backend, the satellite identifier ranges for different satellite systems may intersect. To uniquely identify a satellite, a combination of satelliteIndetifier() and satelliteSystem () must be used.
注意： Getter function for property satelliteIdentifier.
另請參閱 setSatelliteIdentifier () 和 satelliteSystem ().
返迴衛星係統 (GPS、GLONASS...)
注意： This value can be used together with satelliteIdentifier () to uniquely identify a satellite.
注意： Getter function for property satelliteSystem.
